The site itself is great, though.
I developed most of the site on my 15.6 inch laptop running Ubuntu. I just loved Ubuntu's Times New Roman and didn't like its Arial. On Windows it's the opposite. Arial looks much better.
Similarly, blue hyperlinks looked great on my laptop's monitor but they're so-so on other monitors.
And you just confirmed both of my thoughts! There's indeed a great contrast between blue hyperlinks and white background on most monitors. And the font is hideous on Windows too, :-(.
We're going to fix both problems soon. As well, we're analyzing job searches to improve them. There's a lot of room for improvement both on the front-end and back-end.
As far as the general design, I don't want to be too harsh but the website looks a little 2005 to me, if you judge by this (obviously unofficial) scale: http://i.imgur.com/7f24Qfs.jpg. This reddit thread is a great place to find good websites (http://www.reddit.com/r/web_design/comments/2zpk4u/best_site...) but a few quick suggestions would be to toss the plain white background, make the main search box a little more pleasing, making the logo and text a little bigger, and try a more modern design for the actual job list (I would look into something like what hckrnews.com does or one of these http://www.freshdesignweb.com/free-css-tables.html).
Also, and I hate myself for saying this, but you may want to look into using bootstrap (http://getbootstrap.com/). I was originally against it since it makes websites look similar and I generally like to write my own code, it does make it easy to modernize projects.
